Guest bio: Sean Carroll is a theoretical physicist, author, and host of Mindscape podcast.
I swear. He sounds like a really smart and really serious Mark Normand.
Wow, I will never be unable to see Mark Normand now. How have I never noticed that before.
So weird to see people saying Lex is not good at asking questions related to science.
Seems like people forget that Lex has a PhD electrical and computer engineering. Even if it's not a PhD in astrophysics. It's better than the people whose only school is Wikipedia. And is definitely smart enough to "ask questions about black holes".
Maybe he's asking simple questions for us dumb viewers.
i wish lex was as literate in politics as he is in computer science
He is clearly not on the same intellectual playing field as his guests and specifically Sean Carroll.
Fantastic 👍
What happens if you "come" inside a black hole?
What's up with some of these comments? I'm surprised by the amount of science illiteracy in here 😅
Yeah seems like the CZcams algorithm is bringing them in, maybe because of some other guests that have been on this show.
@@steveoscaro your mom
If earth orbited a supermassive black hole, would the night sky change faster than it does currently?
Asking what time is like inside of a black hole is a dumb question…
What I think Lex is questioning is how time at the center might appear relative to an observer outside?
Jump in a black hole and the mini aliens will call you dark matter. Shine light in a black hole and they’ll see dark energy
This man knows too much
Inside every black hole is the state of Kentucky
Middle of a black hole is not kind to our forms of matter at this scale. Space between electron cloud and neutron wayyyyy to big. Reality is all in the gluons which are to never be exposed
Inside black wholes are other universes. We live inside a black whole. Dark energy is just matter bleeding in from the outside into our universe. The cosmological constant is not really a constant. Its value is different for other universes inside black holes and its proportional to their size. The bigger the black hole, the more matter theyre able to pull in and thus more matter bleeds in pushing everything inside it apart faster.
The big bang was just the death of the star that created the black hole we live in. As time passed, more matter bleed in causing our universe to expand and to cool down.
Got ANY evidence for that intellectual diarrea?
I doubt it 😂@@MrDerushingo
I imagine it similar to a dark hallway that gets more narrow by a margin u can barely tell by the time you hit the end could be spit out somewhere
You have to know how fast the Milky Way is moving towards Andromeda and if our entire galaxy cluster is also moving. Then time can be understood
I don't understand why black hole is cold, the more mass it have the colder it is.
A black hole has negative 122,000,900,999 degrees which is referred to as the "black temperature" so it technically doesn't get warm or cold
The Hawking radiation at the event horizon evaporates slower the larger the circumference of the event horizon.
It is because the gravitational time dilation causes everything to appear to be moving slower, as measured from outside the hole. Temperature is the average kinetic energy of an object, measured as mass*velocity^2. Velocity is change in position divided by change in time, dx/dt. If time becomes large, velocity becomes small and thus kinetic energy becomes small and temperature becomes small. Near the singularity, gravity approaches infinity. Thus time dilation approaches infinity, velocity approaches zero, kinetic energy approaches zero, and temperature approaches absolute zero.
@@stt5v2002 almost. Time dilation does not occur until hawking radiation exceeds the "black temperature" at which point the singularity will appear and will continue to become more pronounced akin to a pupil dilating a very small dot to a bigger dot
Ignoring time dilation-which the bh doesn’t give a flying one about from ‘his’ perspective-depending on its age and feeding habits it is essentially still a star and is likely hot as F! Be careful with GR purists with their silly made up mathematics.
His answer to the question was basically an exercise in semantics. The correct answer would be I don't know!
He did say he doesn't know ('nobody went there'), he was addressing the things we do know.
Either we know more about the universe than we are reporting or we really don't know anything and have equations to fill in the blanks of what we actually don't know. Either we went to the moon and expanded our knowledge of the cosmos or we didn't and we just explain what we don't know with a math that hasn't been proven.
@@michaelricucci7646 I'm thinking it's you who doesn't know and/or don't have the capacity to grasp it but too afraid or proud to acknowledge it and then reach out for conspiracy theories.
Imagine actually believing that hundreds of millions of cosmologists and particle physicists from different countries all over the world are all joined in some huge conspiracy and they all are silent about it
Nice one mate
@loopmantra8314 ......do you feel better, mate? Did I say something about a conspiracy theory or intimate there was a cabal of intelligent people in cahoots for the greater evil of our world? No. No I did not, mate. You did though. YOU talked about conspiracies. YOU mentioned a cabal. YOU personalized an inoculous comment on the internet and attempted to insult a stranger. Then you project your own thoughts and ideas and claim I made the statement? Wow. Impressive.
Imagine if all of the astrophysists and exobiolgists in all the lands did work together and share information and we invested money into that rather than....well, many many other more destructive things.
But let's argue on the internet while the world's wealth is spent weaponizing potential research methods that could be put towards actually exploring the cosmos. Lol thank you for being an example of what I was talking about.
Until we become less unhinged by simple conjecture and unglued at the thought of a competitive idea, we couldn't understand the first moment of a universal existence. Have a great day, mate.
You can just admit you don't understand what he's saying, bro
We can never touch a gluon but a black hole mashes them together like a trash compactor, from all directions, faster than the speed of light. Seemingly infinite inwards energy for structures “reality juice”
Hawking radiation is similar to the colliding and spreading of our galaxies at the speed of light on a larger scale
no
@@yonaoisme except it comes off as radiation from the black hole. On a larger scale our galaxy clusters would be radiation in the megastructure universe
@@iguesss none of this intellectual vomit means anything
Compare Sean Carroll to Neil deGrasse Tyson.
If there are quantum black holes, what gets sucked inside, obviously not photons and neutrons, not even 1 could fit
Other quantumn black holes
@@jrbling25 with no particles? What is a particle to us if it doesn’t make it to the any boson frequency anyway
😂😂😂😂 a pair of
A black hole is a worm hole. Once you passed the event horizon you can’t see anything because it’s went through the worm hole
what reason does anyone have to believe this?
@@yonaoisme it wasn’t supposed to be educational. I’m just guessing that’s what it is
@@armandoquintana2185 why are you verbalizing this guess instead of any other sequence of random words? what makes you think that your guess could be right?
I've stated this before, but we've undoubtedly lost a generation or two on the type of GUFF Carroll YAMMERS about. Many of the greatest minds aren't engaged with the problems of this planet. I say let's solve some real problems here until the data comes in from ongoing missions.
Think again. Many of the greatest minds right now are on it and thinking about this stuff 24/7. Sean is one of them. Get out of your own way dude! You are a nobody simpleton, as am I.
Time is messed up because we are moving super fast around the sun that is moving extremely fast in the milky way. Outside of the galaxy time probably moves so fast
no. first of all, we actually know how fast we are moving relative to the microwave background, and it is a tiny fraction of the speed of light. and second of all, speed is relative; we are actually stationary relative to ourselves
@@yonaoisme we cant chart outside the observable universe though. Outside of the observable universe, we are just making guesses of light that flashed a long time ago
@@yonaoisme you are telling me how fast the observable is becoming stretched but the speed at which it becomes in observable is the speed of light. They dont have a universe edge
@@yonaoisme you are literally claiming there is an end of the universe that you could see, you just arent in the right area smh
@@yonaoisme we could all be moving in the same direction for our cluster tho.. you have to factor in everything
Lex is totally unequipped to be talking about black holes, especially with a theoretical physicist!
Says who, you?
Your ilk can’t even define what you are, no one cares what you think.
Move along. ------>
Gotta love polite criticism
I completely disagree. Anyone is allowed. But I think Lex thinks he understands more than he actually does.
That's kind of the point of an interview, is it not? To talk to someone about a topic in which one is NOT an expert?
@@andrewb8074 yehhhh, but he really should have known more at a layman level so that he wasnt asking dumb questions. This was a waste of an interview at parts coz he didnt know the right questions to ask.
Nice "theory" 😂 the whole staying younger moving at the speed of light doesnt even make sense. If youre moving at the speed of light all that means is you get from point A. To point B. Faster. Time doesnt magically slow down. If you set 2 watches on a timer, one left on earth. One on your wrist and you traveled to the edge of the universe and back the timers would still be the same time the only difference would be the space traveled.
This is actually true. In fact, we have to compensate for this on our satellites for our GPS to even work correctly!
@@michaelhart2715 7 microseconds is nothing. it's mostly the time it takes the signal to come back. Nothing to do with speed of the satellite warping time. Like I said the only thing that changes is the distance traveled.
We're all so lucky to have you here to refute Einstein
@@draleigh8881 It has been proven like a million times dude. Even putting an atomic clock on the Concord jet proved that traveling quickly slows relative time down. Saying "seven microseconds is nothing" is hilariously ignorant when you're talking about satellites, which are basically the speed of a tectonic plate compared to the speed of light. You can't even mentally visualize the scale in your own argument. You're very close to basically arguing similarly to a flat earther that just can't comprehend how BIG the earth is.
Go back to school
He is just trying to baffle us with bs, honest answer would be he doesn’t know
Right. More bull shit. No mass exists inside the event horizon. No singularity. He is stuck in a mathematical tar pit.
what evidence you got?
@@yonaoisme I answered you and my comments go poof.
@@yonaoisme A guy asked me one time what's in a black hole. I said, "That's where the light is"
@@proteusaugustus light has mass. didn't you say that no mass exists inside the event horizon??
@@yonaoisme Light and mass are not the same thing. Einstein's equation attempted to unlock the energy within the proton but it is only successful in normalized space and doesn't totally conserve energy. My Tau configuration shows how EMR constructed quantum triangle couples the wave function of the taos in 2 dimensional space to substantiate itself as massive in 3 dimensional space by pulling the quantum field around it. The radius of my proton model is the radius from the center of the triangle to the surface of the 3d quantum field distortion. The proton is made of light that presents itself to us as mass.
I'm shocked at the amount of dumb sh*t that Lex said here. "when a black hole evaporates...after a MILLION years" ....no Lex, it takes many orders of magnitude more than that buddy.
first of all, there are sizes of black holes that indeed do evaporate within millions of years, second of all, 10^80 years is technically millions of years, precisely 10^74 million years. and lastly, that's not "dumb shit" to say, it's just ever so slightly incorrect. you're just so full of yourself that you think that knowing the irrelevant fact of how fast a black hole evaporates makes you smart in any way. but in fact, you demonstrated that you are completely clueless.
They still can’t figure out how many planets are in our own solar system & these guys act like they have a clue what a black hole is 😂
I've seen a few black holes
I know and seen some black holes
That’s because we can’t physically see what might exist beyond our solar system. A black hole is a mathematical certainty of mass, gravity, and time. A black hole and its properties were discovered inside a classroom, not through a telescope.
^ That’s the stock answer from someone who is frustrated they have no idea what they just listened to.
Throw in an emoji to really emphasize their frustration.
these theories are so goofy im sorry. If scientists discover the truth to these questions some day and they were correct about all this i will eat a dog poop
this is nonsense. black holes are where mass and magnitude diverge. it has nothing to do with time or space warpage. within a black hole is essentially dielectricity or inertia or the lack of magnetism. we exist due to magnetism and without it we become inertia or pure cartesian energy.
That makes sense. To whom, I have no idea .
Mass affects the perception of time does it not?
